Description
Technical field
The utility model relates to the Polluted Soil in cement kiln synergic processing living garbage pollution soil project to enter kiln one
A kind of kind application, and in particular to Polluted Soil disposal system.
Background technology
Polluted Soil method of disposal can help to handle town and country Polluted Soil, because incineration temperature is high, residence time length, will not produce
Raw secondary pollution, in view of the characteristics of cement industry itself, will not also produce outer waste discharge slag, accomplish to the complete of contaminated soil
Harmlessness disposing, cement firing process will not be had an impact substantially in itself.Chinese countryside arable land pollution by pesticides and urban industry
More universal with ground contamination, as under the situation of a great problem, the utility model is devised at a kind of Polluted Soil for Polluted Soil disposal
Put system.
Utility model content
In view of the shortcomings of the prior art, the purpose of the utility model is to be to provide a kind of Polluted Soil disposal system,
Incineration temperature is high, residence time length, will not produce secondary pollution, environmentally friendly.
To achieve these goals, the utility model is to realize by the following technical solutions：A kind of Polluted Soil disposal
System, including feed bin, belt conveyor, surge bunker, measuring belt scale, the first weight reprint valve, the second weight reprint valve and lock
Plate valve, feed bin are connected by belt conveyor with surge bunker, are provided with measuring belt scale below surge bunker, under measuring belt scale
Material scraper-trough conveyer is sequentially connected the first weight reprint valve, the second weight reprint valve and slide valve, slide valve and is connected with cement kiln end smoke-box,
Cement kiln end smoke-box is connected with rotary kiln.
Preferably, it is provided with spiral reamer in described feed bin.
Preferably, described belt conveyor is high angle belt conveyer conveyer.
Preferably, maximum temperature is 1800 DEG C in described cement kiln end smoke-box.
Preferably, described rotary kiln is alkaline rotary kiln.
Preferably, described spiral reamer is connected with electric rotating machine.
Preferably, described surge bunker is buffering uniformizing bin.
The utility model has the advantages that：
（1）Flue gas and temperature of charge highest respectively reach 1800 DEG C and 1450 DEG C in cement kiln, organic in contaminated soil
Pollutant destroys rate by fire up to more than 99.9999%.
（2）Total residence time of the material from kiln tail to kiln hood is more than 30 minutes, and gas is in the stop higher than 1300 DEG C of temperature
Time is more than 10 seconds.
（3）High-temperature gas is in opposite direction with Flow of Goods and Materials in cement kiln, and turbulent flow is strong, is advantageous to the mixing of gas-solid phase, passes
Heat, mass transfer, decomposition, chemical combination, diffusion.
（4）The alkaline environment of cement kiln can neutralize caused acidic materials in Polluted Soil disposal process（Such as HCl, SO2And CO2
Deng）；
（5）During cement kiln calcining waste, it can be kept away by most heavy metals immobilizations in waste in clinker
The diffusion once again of heavy metal is exempted from；
（6）In the technical process of manufacture of cement, clinker, all waste only caused by raw material and process calcine technology
Thing is all decomposed or is cured in cement lattice, and the problem of producing clinker is burned without general incinerator；
（7）Cement industry firing system and exhaust treatment system, make waste gas after burning by longer path and good
Good cooling and dust collection device, there is higher absorption, settle and the effect of gathering dust.The dust of collection returns former by induction system
Material preparation system can re-use；
（8）New dry process rotary kiln running efficiency is high, and general year running rate is more than 90%, burns in stable condition, incineration disposal
Amount is big, and speed is fast.
Brief description of the drawings
Describe the utility model in detail with reference to the accompanying drawings and detailed description；
Fig. 1 is structural representation of the present utility model.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
Reference picture 1, present embodiment use following technical scheme：A kind of Polluted Soil disposal system, including feed bin 1,
Belt conveyor 2, surge bunker 3, measuring belt scale 4, the first weight reprint valve 5, the second weight reprint valve 6 and slide valve 7, feed bin
1 is connected by belt conveyor 2 with surge bunker 3, and the lower section of surge bunker 3 is provided with measuring belt scale 4, the blanking of measuring belt scale 4
Scraper-trough conveyer is sequentially connected the first weight reprint valve 5, the second weight reprint valve 6 and slide valve 7, slide valve 7 and the phase of cement kiln end smoke-box 8
Even, cement kiln end smoke-box 8 is connected with rotary kiln 9.
The system job step of present embodiment is：1）It is sent into by the Polluted Soil of feed bin 1 with spiral reamer discharging
High angle belt conveyer conveyer 2.
2）Polluted Soil is sent into by surge bunker 3 by high angle belt conveyer conveyer 2.
3）Measuring belt scale 4 is dumped into by surge bunker to be measured.
4）Blanking scraper-trough conveyer is discharged into after measuring belt scale metering, passes through the first weight reprint valve 5, the and of the second weight reprint valve 6
Slide valve 7 enters cement kiln end smoke-box.First weight reprint valve 5, the second weight reprint valve 6 and slide valve 7 then ensure cement
Kiln system does not leak out.
5）Last Polluted Soil enters cement rotary kiln 9, contained using the high temperature in kiln and the decomposition of longer residence time
Organic Hazardous Compounds, solidifying the utility such as heavy metal therein, Ca, Si, Al, Fe therein becomes the original of clinker
Material.
It is worth noting that, gas phase temperature reaches as high as 1800 DEG C in cement kiln, temperature of charge is about 1450 DEG C, in cement
Under the hot conditions of kiln, the organic pollution in contaminated soil is converted into inorganic compound, high temperature gas flow and high fineness, highly concentrated
